Miriam was a little surprised. She knew that her husband was clever with his tools, but she had never set any value on his labours. Now, however, she was really struck with the well-polished mahogany and the piece of brass neatly let into the lid, and when she heard Mr. Armstrong's praises she began to think a little differently.
"Ah!" he continued, "it is so difficult now to get anybody to take any interest in such a job as that. I have got another box at home made by a professed cabinetmaker, and it is really disgraceful. It will never be right, although I have had it altered two or three times. When it was shut it caught the object-glass inside. I remedied that defect, but only to create a worse, for then the instrument shook about. So it is, when once a thing is badly done, you had better get rid of it; it is of no use to bother with it. You may depend upon it, it is not bad just here or there, but is bad all through, and the attempt to mend it serves no other purpose than to bring to light hidden weakness. On the other hand, if you are fortunate enough to have work done like Mr. Farrow's, it is perfect all through. You can never surprise it, so to speak. Just look at it. Look at that green baize rest. There is not the thirty-second part of an inch to spare on either side, and the lid comes down so evenly that you can hardly see where the edge is. Shake the box, and you will not feel a single movement. You have never seen my big telescope at Marston?"
"No."
"Well, if you like, you can come over with your husband any bright night, and I shall be happy to show it to you."
Miriam thanked him, and they parted.
A few days afterwards Mrs. and Mr. Farrow presented themselves at the vicarage. It was a lovely evening, and so clear that the outline of the constellations was obscured by the multitude of small stars, which usually are not seen, or seen but imperfectly. In the south was Jupiter, mild, magnificent, like a god amongst the crowd of lesser divinities.
Mr. Armstrong, with all the ardour of an enthusiast for his science, began a little preliminary lecture.
"I am not going to let you peep simply in order to astonish you. I abominate what are called popular lectures for that very reason. If you can be made to understand the apparent revolution of the heavens, that is better than all speculation. To understand is the great thing, not to gape. Now I assume you know that the earth goes round on its axis, and that consequently the stars seem to revolve round the earth. But the great difficulty is to realise how they go round, because the axis is not upright, nor yet horizontal, but inclined, and points to that star up there, the pole-star. Consequently the stars describe circles which are not at right angles with the horizon, nor yet parallel to it. That is my first lesson."
Mr. Farrow comprehended without the slightest difficulty, but Miriam could not. She had noticed that some of the stars appear in the east and disappear in the west, but beyond that she had not gone. Mr. Armstrong continued—
"The next thing you have to bear in mind is that the planets move about amongst the stars. Just think! They go round the sun, and so do we. The times of their revolution are not coincident with ours, and their path is sometimes forwards and sometimes backwards. Suppose we were in the centre of the planetary system, all these irregularities would disappear; but we are outside, and therefore it looks so complicated."
